To all whom t may concern:

Be it known that I, JOHN J. Znrrz, citi- Zen of the United States,residing at Warren, in the county of Trumbull and State of Ohio, haveinvented certain new and useful Improvements in Stacking Mechanism inPaper-Folding Machines, of which the fol# lowing is a specification.

This invention appertains to a stacking mechanism for paperfoldingmachines, and

to be used with a folding machine invented by Albert D. Pejano and JohnJ. Zeitz, and patented June 9, 1914, Nc.'1,099,884.

In the accompanying drawings, Figure 1 is a rear elevation of themachine showing the stacking mechanism at the middle of the machine witha directly downward feed.

Fig. 2 is a horizontal view von a sectionaly line just above thestacking table and showing the said table adjusted to the right of themachine and with the folding head and its rollers in a vertical positionto deliver at -its side. Fig. 3 is a side elevation of the machineshowing the reverse side from Fig. 4. Fig. 4 is a vertical sectionalelevation on the axis of the folder head and corresponding substantiallyto line 4-;l, Fig. 2. Flg. 5 `is a sectional plan view of the machine.Fig. 6 is a sectional View of a detail herein- Thepresent inventionbeing limited to the stacking portion of the machine herein shown thedescription which follows will be correspondingly7 confined to thestacker alone except as may be necessary to make the entire operationintelligible. Furthermore, it will be understood that stackers, as

such, in connection with paper folding machines are not at this time abroadly new conception and a form thereof is shown in the above namedapplication, but the particular stacking mechanism contained herein isbelieved to be entirely new and patentable and has been found bothsimple and effective for doing the work. To these ends the saidmechanism comprises a stacking table a upon which the folded sheets aredelivered from between the last two rollers r of the series of feedrollers shown, and are received on-said table so rapidly that thepassage of the paper from the rolls to the table is diiicult to followwith the eye, and such delivery is edgewise upon said table nextinadvance of the stop or head h.

against which the stack is pressed by the stacker and is further heldas'hereinafter described'. The said head or stop h isa fairly heavypiece of castmetal, preferably,

"and slidable in a'slot in the table, the weight however, being suchthat it can be pushed back by the positive pressure of the stacker a asthe stack accumulates before it on the When the said stop reaches therear table. end of the table the machine is momentarily stopped. toremove the sheets, when operations are again resumed after sliding thesaid stop inward to the starting point.-

The stacker s, so called, or part which carries the sheets forwardsuccessively as they come through the rolls 7 to or against the table a,or rather the said stacker is vertically adjustable by check c engagingthe stem 2 through a head d which carries the stacker and travels backand forth in said slot in the" table.

` stop 71 is adapted to have a back and forth Actuation of the stackerproceeds pri--v marily from a cam c mounted on a shaft 3 at the rear ofthe machine and is supported relatively beneath or from the table @bymeans of a suitable bracket b. The said cam-is preferably of disk shapeand has a cam groove or channel 4 in the side thereof in which a roller.or wheel 5 on lever 6 is operatively engaged. The said lever is pivotedat its' lower end in the bracket or hanger I) fixed inthe bottom oftable a and has said roller 5 near its middle while the stackeractuating link connections 8 engage the upper end ,of said lever andproceed thence to stacker supporting head d through a sleeve or othersuitable support 7c on the bottom of the table. The cam c thus governsthe throw of the stacker and by said cam the to and fro movementsthereof are made positive within fixed limits.

The cam shaft 3 is parallel to shaft 9, and idler shaft 10 intervenesand a train of gears, g g and g2 communicate power from shaft 9 to shaft3. The said shaft 9 may be connected up with the driving power of themachine by any suitable means, such, for example, as by the dependingshaft 12, Fig,

1, and bevel gears 13 at the junction thereof With shaft 9, or by anyother suitable train of power connections.

. The table a is both vertically and laterally adjustable according tothe Work to. be done, and may be positioned at the middle ofthe machineas seen in Fig. 1, or at the side as seen in Fig. 2, and is slidablelaterally in ror upon the cross frame or b'ar 14 beneath and locked hereor there by bolt b', Fig. 4. The said cross support 14 extends betweenthe two vertically disposed'channel iron posts or standards 15 of themain frame of the machine and the adjusting screws 16 are in relation toengage in sleeve nuts ,in thecends of the said cross-bar or frame andserve to fix the elevation thereof. The said screws are themselvesjointly controlled by` a trans- Versely disposed shaft 20- carryingbevel or miter gears 21 meshing with similar gears 22 on the respectivescrews 1'6, Iand adapted to turn the l'same to effect the up and downmovements of the said table support 14 and the ,parts carried thereby asthe different kinds of work may require, the folds being of varyingdepth or width and requiring correspondingly different elevations oftable a.

` The elevation of` a table a being determined through the "foregoingmechanism the folded stock is delivered thereon and stacked against thestop or block h as hereinbefore described and held when the stackerretires by the spring pressed fingers fin the said table.rv `Theselingers are .pivoted to allow the paper to be pushed over them by thestacker in its forward movement but under spring pressure they instantlyassume the upright position shown in Fig. 4 when the stacker retires andhold sheets in stacked'V position. Asl a matter' of practice the stop itis up fairly close to the outer set of lingers when the stacking begins,and it is gradually pushed back asY the size of the stack increases,until at last the said stop is carried gradually to the rear of thetable where aI bell may be placed to be rung by contact by the stop totell that the table is full. As the stack increases in size it coversthe outer set of fingers and the inner set come into action. a

A pair of side arms m have sheet spring or equivalent fingers orprojections n in their ends which coperate with the lingers f insustaining the folded stock on the table,

and said arms serve also as means for alining or confining the stockwithin limits at the ends thereof. The said arms are verticallyladjustable in right angled brackets 25, and said brackets are laterallyadjustable in slot 26 beneath and extend laterally in respect to thetable.

It should be understood that the rotatable head 30 which carries thefeed rollers 1' is rotatable on its axis 31 so as t0 feedthe foldedstock directlydownward, as in Fig. i

the stacking table carries all the stacking mechanism, and the shaft 9is splined so that gear g thereon may slide to accommodate the movementsof the table to center or side of the machine, and actuate the cam cwhether in one position or the other. The present invention thereforehas only one packing table, slidably mounted on bar or rail 14 and canbelocated to do its work in" any position from one end of said rail tothe other. cated at either extreme for right angle work, and when in themiddle for parallel work, the packing table and rail are raised andlowered with a screw, making it convenient for 'the operator to adjustit for height, etc. c

The stacker or jogger s is positively actuated back and forth by a slotcam, eliminating va spring return and unnecessary friction and work,thereby greatly increasing the life of same, and making it durable andpractical. rEhis yalso is a desirable feature in that it prevents adelivered sheet from interfering wit-h the nextone by pushing thealready delivered sheet completely out of the waybehind the iioppers nin the side retaining arms my and Hoppers or fingers f in bedof frame.All'the mechanism for actuating the jogger is contained and fastened toframe 14 except the rotating means, such as shafts and beveled gears.

What l.' claim is:

1. A- stacking mechanism for paper folding machines having a stackingtable adjustable vertically and laterally, a stacker at the inner end ofsaid table, a cam wheel mounted on said table and an operating leverengaged therewith, and links connecting said lever with said stacker andadapted to reciprocate the same over said table. 4

2. A paper folding machine and a single stacking table vertically andlaterally adjustable, yin combination with stacking means mounted uponsaid table and adjustable therewith, said means comprising a slidablestop for the folded product, pivoted fingers in said table in advance ofsaid stop, an arm at each side of said table and relatively above thesame and a reciprocating stacker.

3. A stacking mechanism for paper folding machines comprising a singlestacking table and Operating mechanism carried 'thereOn to Stack thefolded papers, a botlil@ . tom supportV and means for adjusting thetable and operating mechanism laterally on said support thereby settingthe table cable stacking means carried thereon, a bottom support andmeans between said parts by which the said table and stacking means arelaterally adjustable, in combination with mechanism at both sides of themachine tov raise and lower said support according to the elevationdesired for the said table,
